This is the second time that I have had this happen. I cant seem to figure it out.

Its coming from the front left of my car while I am sitting in it. Basically directly in front of me. It sounds like a squeek but its not.

Like I have a leak in one of my lines and when I get on it hard it bleed through. I wouldnt know what that sounds like, but could that be it?

It has only happened twice. At first I thought it was in my suspension but its definately not.

Its just a quick pretty loud whistle or squeek that lasts a second.

Now I am thinking maybe a seal is getting ready to give and god I hope that isnt it.

Any Ideas Guys???

 

try changing out your belts.

 

it could also be one of the pullies or mabey the power steering pump. i know you said it wasnt a squeak but its just a thought.

 

At what Rpm would you say it happened at?

 

I would say right as 2nd turbo kicks on.

 

Car still drives like it usually does no change in boost. Could be a belt but its suck a quick and random noise.

Sounds alot more like blowing through a straw with a hole in it. Not a squeek...

 

My mods if it helps are. DP, MP, clutch, flywheel, bost / water gauge

I also noticed a small spiking but I am getting boost controller or pfc very soon..

 

bump

 

I have that problem too. It squeeks every now and then when I punch it, but then again it does it even when I'm just cruising (could be a different noise). I also thought it was a suspension issue. Anybody got a clue of what is causing it?

 

I used to get some kazoo-like noises right on the edge of making boost while cruising. I think it was just some kind of resonance in the intake tract somewhere. I haven't heard it for a while, but I changed a lot of the intake parts and I am not sure which change eliminated the problem.
